ADVANCED SULFUR CONTROL CONCEPTS FOR HOT GAS DESULFURIZATION TECHNOLOGY

Description: The objective of this project is to develop a hot-gas desulfurization process scheme for control of H{sub 2}S in HTHP coal gas that can be more simply and economically integrated with known regenerable sorbents in DOE/METC-sponsored work than current leading hot-gas desulfurization technologies. In addition to being more economical, the process scheme to be developed must yield an elemental sulfur byproduct.

Char Crystalline Transformations During Coal Combustion and Their Implication for Carbon Burnout

Description: Recent work at Sandia National Laboratories, Imperial College, and the U.K. utility PowerGen, has identified an important mechanism believed to have a large influence on unburned carbon levels from pulverized coal fired boilers. That mechanism is char carbon crystalline rearrangements on subsecond times scales at temperatures of 1800 - 2500 K, which lead to char deactivation in the flame zones of furnaces. The so-called thermal annealing of carbons is a well known phenomenon, but its key role i… more

Advanced Reservoir Characterization and Evaluation of CO2 Gravity Drainage in the Naturally Fractured Spraberry Reservoir

Description: Natural fractures exert a strong influence over oil production in Spraberry Trend Area reservoirs in the Permian Basin of west Texas. The importance of the fracture network has been known since the 1950s, but until recently, there has been very little detailed study of the fractures themselves. In 1996, a horizontal Spraberry well was cored as part of a DOE Class III Field Demonstration Project. Fractures from the horizontal core as well as other fractures encountered in vertical Spraberry core… more

Hindered Diffusion of Asphaltenes at Evaluated Temperature and Pressure

Description: During this time period, uptake experiments were performed at elevated temperatures up to 280 o C for the adsorptive diffusion of a coal asphaltene in 1- methylnaphthalene onto alumina catalyst pellets. Model simulation results showed that a mathematical model incorporating diffusion and adsorption mechanisms satisfactorily fitted the adsorptive diffusion of coal asphaltenes onto the alumina catalyst in a fairly wide temperature range of 55 o C to 280 o C. The logarithm of the adsorption consta… more

Detailed Gravity and Magnetic Survey of the Taylorsville Triassic Basin

Description: Our research to date has involved the Interpretation of the Bouguer Gravity Anomaly Associated with the Richmond and Taylorsville Triassic Basins and its Vicinity. Continental rift basins around the world contain about 5% of the earth's sedimentary layers and produce about 20% of the total hydrocarbon production of the world (Ziegler (1983). Nearly 30 large basins of this type are reported by Manspeizer and Cousminer (1988) in eastern North America and northwestern Africa. There are eleven expo… more

Design and Fabrication of the First Commercial-Scale Liquid Phase Methanol (LPMEOH) Reactor

Description: The Liquid Phase Methanol (LPMEOHT) process uses a slurry bubble column reactor to convert synthesis gas (syngas), primarily a mixture of carbon monoxide and hydrogen, to methanol. Because of its superior heat management the process can utilize directly the carbon monoxide (CO)-rich syngas characteristic of the gasification of coal, petroleum coke, residual oil, wastes, or other hydrocarbon feedstocks. The LPMEOHM Demonstration Project at Kingsport, Tennessee, is a $213.7 million cooperative ag… more

Engineering Development of Coal-Fired High-Performance Power Systems

Description: The concept uses a pyrolyzation process to convert coal into fuel gas and char. The char is fired in a High Temperature Advanced Furnace (HITAF). It is a pulverized fuel- fired boiler/ air heater where steam and gas turbine air are indirectly heated. The fuel gas generated in the pyrolyzer is then used to heat the gas turbine air further before it enters the gas turbine. The project is currently in Phase 2 which includes engineering analysis, laboratory testing and pilot plant testing. Research… more

Mechanisms and optimization of coal combustion. Semiannual report, November 1, 1998--April 30, 1999

Description: The effects of process conditions on the reactivity of Illinois No.6 coal in the kinetic and diffusion control regime were studied using new sequential combustion procedures. Reactivity patterns in the kinetic controlled regime were not influenced by the pyrolysis heating rates. Results presented in the previous DOE report have shown, however, that combustion rates were significantly affected by the pyrolysis heating rates at reaction temperatures higher than 550 C. These results establish the … more

Alternative fuels and chemicals from synthesis gas

Description: A DOE/PETC funded study was conducted to examine the use of a liquid phase mixed alcohol synthesis (LPMAS) plant to produce gasoline blending ethers. The LPMAS plant was integrated into three utilization scenarios: a coal fed IGCC power plant, a petroleum refinery using coke as a gasification feedstock, and a standalone natural gas fed partial oxidation plant. The objective of the study was to establish targets for the development of catalysts for the LPMAS reaction. In the IGCC scenario, synga… more

Toxic Substances From Coal Combustion

Description: The Clean Air Act Amendments of 1990 identify a number of hazardous air pollutants (HAPs) as candidates for regulation. Should regulations be imposed on HAP emissions from coal-fired power plants, a sound understanding of the fundamental principles controlling the formation and partitioning of toxic species during coal combustion will be needed. With support from the Federal Energy Technology Center (FETC), the Electric Power Research Institute, the Lignite Research Council, and VTT (Finland), … more

Cross flow flotation column for coal and minerals beneficiation

Description: An apparatus and process are disclosed for the separation of coal from pyritic impurities using a modified froth flotation system. The froth flotation column incorporates a helical track about the inner wall of the column in a region intermediate between the top and base of the column. A standard impeller located about the central axis of the column is used to generate a centrifugal force thereby increasing the separation efficiency of coal from the pyritic particles and hydrophilic tailings.

Mechanisms and optimization of coal combustion. Semiannual report, May 1, 1998--October 31, 1998

Description: The effects of process conditions on the reactivity of Illinois No. 6 coal were studied using a new sequential combustion procedure. This procedure was developed to accurately simulate the reacting zones of industrial coal combustors. Reactivity patterns in the diffusion controlled regime were significantly affected by the pyrolysis heating rates, as well as by the oxygen concentration and combustion temperature. These results clearly show the importance of the macropore structure of chars in d… more

Feasibility study for lowering the minimum gas pressure in solution-mined caverns based on geomechanical analyses of creep-induced damage and healing

Description: Geomechanical analyses were made to determine the minimum gas pressure allowable based on an existing stress-based criterion (Damage Potential) and an advanced constitutive model (MDCF model) capable of quantifying the level of damage and healing in rock salt. The MDCF model is a constitutive model developed for the WIPP to provide a continuum description of the dislocation and damage deformation of salt. The purpose of this study was to determine if the MDCF model is applicable for evaluating … more
